expand x^2sqrt(1+(2x)^2)

expand

x^{2} 1 + (2 x)^{2}

x^{2} 1 + 4 x^{2}

Solution steps

x^{2} 1 + (2 x)^{2}

1 + (2 x)^{2} = 1 + 4 x^{2}

= x^{2} 4 x^{2} + 1

(- 2, 3, 4) y (2, - 3, 5)

(x - \frac{5}{2}) \cdot (x + \frac{5}{2})

\frac{9 ( - e ^{2} + 1 )}{10 ( e ^{2} + 9 )} + 1

(t cos (t) + 2 sin (t))^{2}

\frac{x ^{2} - 9}{x ^{2} ( x + 4 )}
